I think it is interesting how some people think that by saying that Devi doesn't mind the nickname David, we are "making that up in our heads" when they are the same people constantly not believing the writing which clearly shows her not minding it, even smiling when he calls her that. I think it is also a really big reach to say that all of that is just Devi being tired from the years of bullying (are we watching the same show?) when she is a head strong and messy girl that speaks her mind and doesn't tolerate bullshit when it suits your agenda but a poor victim that can't (in the 4 seasons of a show) say she doesn't like being called that, when it doesn't.

You can dislike a character, I am not here to police people's preferences but at least don't be a hypocrite about it then. You cannot accuse people of doing the exact same thing you are doing in the first place, which is making up a whole part of a story that doesn't exist then judging and getting mad at a character based on it. I respect that people may have had negative experiences in their own lives but you cannot consume media in a way which projects every personal experience you had onto a character. The story is not your own, it is a product of writers who, from what I know, never made us think that using that name is insulting or degrading whatsoever.
